| titleOfInvention | A kind of MEMS hydrogen sulfide sensor and preparation method for improving metal salt poisoning effect |
| abstract | The invention discloses a MEMS hydrogen sulfide sensor and a preparation method for improving the poisoning effect of metal salts, and relates to the technical field of hydrogen sulfide sensors based on organic/inorganic composite nanomaterials, so as to solve the problem of high problems in the preparation of existing anti-poisoning hydrogen sulfide gas sensors. Technical problems of energy consumption or complex synthesis process. The sensor includes a substrate, interdigital electrodes, and an acidic polymer/metal salt composite sensitive film attached to the surface of the interdigital electrodes. On the one hand, the hydrogen ions contained in the composite sensitive film of the present invention form a competitive doping with metal ions to affect the conductivity of the sensitive material, that is, in the hydrogen sulfide atmosphere, metal ion de-doping and hydrogen ion substitution doping jointly promote the self-discharge of the sensitive film itself. On the other hand, during the sensor recovery process, an acidic environment is provided to promote the re-conversion of metal sulfides into metal salts in the air, so that the sensor can return to its original state. |
